After STZ injection, levels of blood glucose in the Model, Liposome, Hirudin and the Hirudin/liposome complex groups were significantly higher compared with the Control group, although the hirudin/liposome complex treatment did not lead to a decrease in the blood glucose level in DN rat models. Control group (n = 10), model group (n = 7), liposome group (n = 7), hirudin group (n = 8), hirudin/liposome complex group (n = 7):P<0.05;*:P<0.01
